Abstract
A method for preparing a sample for analysis includes separating a gas sample into at least one component sample in a separation unit. The output of the at least one component sample from the separation unit is detected, for example, using a thermal conductivity detector. A hydrocarbon in the component sample is combusted in a combustion unit to generate a combustion product. The at least one component sample is collected in a sample collector and supplied to an analysis unit. In some embodiments, the analysis unit may be used to determine an isotopic ratio of the at least one component sample.

A method of preparing a sample for analysis, comprising:
- separating a gas sample into at least one component sample in a separation unit;
- detecting an output of the at least one component sample from the separation unit;
- combusting a hydrocarbon in the at least one component sample in a combustion unit to generate a combustion product;
- collecting the combustion product in a sample collector;
- and
- supplying the collected combustion product to an analysis unit.
A method of analyzing mudgas components, comprising:
- supplying a mudgas sample to a gas chromatograph to separate the mudgas sample into different components on the basis of component elution times;
- detecting an output of at least one component of the mudgas sample from the gas chromatograph using a thermal conductivity detector;
- supplying the at least one component to a combustion chamber and combusting a hydrocarbon in the at least one component to form a combusted component sample including at least one of carbon dioxide and carbon monoxide;
- collecting the combusted component sample in a sample collection unit;
- and
- supplying the combusted component sample from the sample collection unit to an analysis unit.
